## Summary

JS Solar, operating under the corporate name Jiangsu Jinshang New Energy Technology and the jssolar.com brand, is a China-based manufacturer headquartered in the Jiangsu region that has been active since the mid-2000s. The company reports annual export volumes of roughly 2 GW of modules plus 2 GW of cells and wafers, and its panels hold TUV SUD certification for PID, salt mist and ammonia corrosion resistance alongside standard CE, RoHS, IEC 61215/61730 and MCS approvals. Solar N Plus (Solar N Plus New Energy Technology) is a vertically integrated manufacturer running three production bases in Siyang, Chuzhou and Dongchuan, with roughly 20 GW of available capacity and another 10 GW under construction, making it a substantially larger operation than JS Solar; in late 2024 it signed an export agreement to supply 500 MW of N-type modules to overseas markets. Neither brand shows up unambiguously on current BloombergNEF Tier 1 lists, so bankability should be confirmed project by project, but on production scale and vertical integration Solar N Plus has the clearly stronger institutional footprint.

JS Solar's catalog centers on conventional monocrystalline modules well suited to residential rooftop installs and smaller commercial jobs, and its salt-mist and ammonia-corrosion certifications make it a reasonable fit for coastal or agricultural sites with harsher environmental exposure. Solar N Plus builds its lineup around N-type TOPCon cell technology, which offers a lower temperature coefficient and reduced LID/PID degradation, making it better suited to utility-scale ground-mount farms and larger commercial and industrial projects where long-term energy yield matters most. For a typical residential buyer, the two brands are largely interchangeable in terms of basic performance, but for larger PV plants or C&I procurement, Solar N Plus is the more defensible default given its greater manufacturing scale and newer cell technology, provided a local distributor can confirm current bankability status and warranty support.
